Abstract

The invention discloses a method and device for directly querying structured data, and the method comprises the following steps: carrying out the validity check according to a data query request transmitted by a user agent, and generating an effective data query statement; executing according to the effective data query statement to obtain a query result; and writing the socket according to the query result to obtain response output of the query result. The embodiment of the invention provides a method and device for directly querying structured data. By introducing new lsql, rsql and rsqls graphs, a method for directly accessing a local or remote database and executing SQL statements is provided for an HTML webpage, and the code quantity for writing a front-end script program or a background server program is reduced. Therefore, by implementing the method and the device, the technical problems that an extra script program needs to be written when the structured data is operated and the occupied memory is relatively large in the prior art are solved.

Description

technical field [0001] The invention relates to the technical field of webpage front ends, in particular to a method and device for directly querying structured data. Background technique [0002] The front end of the webpage is a webpage that runs on browsers such as PCs and mobiles and is displayed to users for browsing. Front-end technology is generally divided into front-end design and front-end development. Front-end design can generally be understood as the visual design of the website, and front-end development is the front-end code implementation of the website, including basic HTML (Hypertext Marked Language, Hypertext Markup Language) and CSS (Cascading Style Sheets, Cascading Style Sheets,) and JavaScript / ajax. [0003] Before HTML 5, the browser can only access the database through the HTTP server, and cannot directly operate the local database (only a simple local storage mechanism such as Cookie is provided). In HTML 5, interfaces for accessing local storage ...
